https://devzone.nordicsemi.com/f/nordic-q-a/96528/receive-mqtt-signals-directly-from-aws-on-thread-end-deviceHello, I am working on a thread based project for a class and I was wondering if it was possible to receive an MQTT packet directly from AWS through the border router? Or is it required to use MQTT-SN with a MQTT broker on the border router.

If you are using nRF 5, <a href="https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/nrf-connect-sdk-and-nrf5-sdk-statement">I would recommend you to switch</a>.</p> <p>Given that you are using NCS, I would not use MQTT-SN. It is difficult. Use MQTT instead.</p> [quote user=""]possible to receive an MQTT packet directly from AWS through the border router?[/quote] <p>This might require the Thread device to have a public IP, but you could get around that. For MQTT, the Thread device will subscribe to a MQTT Broker. And since the device have subscribed &quot;via a TCP connection&quot;, the Broker likely do not need to know the address of the Thread Device.</p> <p>Regards,</p> <p>Elfving</p><div style="clear:both;"></div>
